In 2003, the teaching staffs behind the Butler-Fearon and the O’Connor-Kennedy Schools realized something: though both academies nurtured the physical, mental, and competitive skills of scores of young Irish dancers, they could form a more robust program by combining forces. Once united, the team of Rose Fearon, Vincent O’Connor, and Kathleen O’Connor—each a certified Irish dance adjudicator—implemented a revised curriculum reaching students from both American coasts to the solid-ice skyscrapers of Ontario. Today, Butler-Fearon-O'Connor trains everyone from girls buckling their jig shoes for the first time to experienced adults, many of whom—such as 2011 world champion Emily Penner—have danced competitively at home or across the pond and landed spots on touring companies for shows such as Riverdance.

Focusing on perfecting traditional form and technique, classes are kept as small as possible, ensuring personalized attention from one of the school's 10 experienced, decorated instructors. Students also learn stamina, flexibility, and presentation, with an emphasis on avoiding motions that tend to draw judges' ire, such as clumsy arm placement and badgering the audience. Many locations also host more casual classes for adults and groups such as Girl Scout troops.
